-=== Dynamic mapping error when trying to add a watch
-
-If you get the _Dynamic Mapping is Disabled_ error when you try to add a watch,
-verify that the index mappings for the `.watches` index are available. You can
-do that by submitting the following request:
-
-[source,js]
---------------------------------------------------
-GET .watches/_mapping
---------------------------------------------------
-// CONSOLE
-
-//When testing is enabled, test [setup:my_active_watch]
-
-If the index mappings are missing, follow these steps to restore the correct
-mappings:
-
-. Stop the Elasticsearch node.
-. Add `xpack.watcher.index.rest.direct_access : true` to `elasticsearch.yml`.
-. Restart the Elasticsearch node.
-. Delete the `.watches` index:

-[source,js]
---------------------------------------------------
-DELETE .watches
---------------------------------------------------
-// CONSOLE
-
-//When testing is enabled, test[skip:index deletion]

-. Disable direct access to the `.watches` index:
-.. Stop the Elasticsearch node.
-.. Remove `xpack.watcher.index.rest.direct_access : true` from `elasticsearch.yml`.
-.. Restart the Elasticsearch node.

-=== Unable to send email
-
-If you get an authentication error indicating that you need to continue the
-sign-in process from a web browser when Watcher attempts to send email, you need
-to configure Gmail to
-https://support.google.com/accounts/answer/6010255?hl=en[Allow Less Secure Apps to access your account].
-
-If you have two-step verification enabled for your email account, you must
-generate and use an App Specific password to send email from {watcher}. For more
-information, see:

-=== {watcher} not responsive
-
-Keep in mind that there's no built-in validation of scripts that you add to a
-watch. Buggy or deliberately malicious scripts can negatively impact {watcher}
-performance. For example, if you add multiple watches with buggy script
-conditions in a short period of time, {watcher} might be temporarily unable to
-process watches until the bad watches time out.
